I started building my first computer. The graphics card requires 2x 8pin power connectors. If I use 2 Vga cords I get no picture and the monitor stays black. If I use my pci-e with a 8pin and 6 pin. I get a picture. If I use the pcie and the vga I get no picture. I don’t want to use the just the pcie because I don’t want to risk anything because I’m missing 2 pins. Why does this happen? What could I do? Should I just use the pci-e? Note: the graphics card does light up.

First of all, vga isn't a power connector, it is a data cable that gives your monitor display.
I believe it should be safe to use the 8-pin and 6-pin, but you may get a decrease in performance or thermals (don't take my word on this). If you really want to be safe, just get a new psu that has 2 8 pin pcie cables.

Are you sure you're not looking at the end of the cable that goes into the power supply itself, which is sometimes labled VGA?

The exact PSU would be a big help here. Otherwise, we're guessing about cables we can't possibly see.

I can find threads about VGA cables on the PSU which act like the same as a PCIE cable but the threads are from 2014. So this must be an old PSU.
